The minimum weighted dominating set (MWDS) problem is one of the classic NP-hard optimization problems in graph theory with applications in many fields such as wireless communication networks. MWDS in general graphs has been showed not to have polynomial-time constant-approximation if $${\mathcal{NP} \neq \mathcal{P}}$$ . Recently, several polynomial-time constant-approximation SCHEMES have been...
In view of the need for highly distributed and federated architecture, ranking ontologies from different data sources in a specific domain have great impact on the performance of web applications. Since ontologies for a same domain usually overlap, we aim to rank ontologies based on the commonality of overlapping entities and distance between each pair of ontologies. Overlapping entities are determined...
